TABLE 2.
Age, gender, and hemodynamic characteristics of the groups matched by age and sex
| Healthy subjects (N = 18) | HT patients (N = 18) | p | |
|---|---|---|---|
| Age (years) | 51.7 ± 14.9 | 53.2 ± 14.4 | 0.760 |
| Male/female | 13/5 | 11/7 | 0.480 |
| BMI (kg/m2) | 24.4 ± 4.0 | 24.0 ± 4.3 | 0.777 |
| SBP (mmHg) | 112.2 ± 7.5 | 141.0 ± 14.0 | < 0.001 |
| DBP (mmHg) | 66.8 ± 9.1 | 85.9 ± 14.8 | < 0.001 |
| HR (beats/min) | 68.1 ± 12.6 | 74.1 ± 11.4 | 0.143 |
| AVI (AU) | 18.2 ± 4.9 | 23.8 ± 6.1 | 0.004 |
| API (AU) | 25.5 ± 7.2 | 31.2 ± 8.6 | 0.028 |
| BF (bursts/min) | 26.3 ± 7.3 | 32.9 ± 13.3 | 0.077 |
| BI (bursts/100 heartbeats) | 41.1 ± 9.6 | 45.8 ± 12.1 | 0.208 |
Values are mean ± SD. Subjects in the healthy and HT groups were matched according to age and BMI by their propensity score using a tolerance value of 0.077.
Abbreviations: API, arterial pressure‐volume index; AU, arbitrary unit; AVI, arterial velocity pulse index; BF, burst frequency; BI, burst incidence; BMI, body mass index; DBP, diastolic blood pressure; HR, heart rate; SBP, systolic blood pressure.
